ToBoGGAN..

SPECIFICATION forming part of Letters Patent No. 340,731, dated April27, 1886.

Application filed March lJ, 1886.

To all whom it may concern.-

Beit known that we, LAWRENCE M..PRoo 'ron and VILLIAM H. PRocToR,citizens of the United States, residing at Ogdensburg, in the county ofSt. Lawrence and State of New York, have invented certain new and usefulImprovements in rloboggans, offwhich the fol` lowing is a specification,reference being had to the accompanying drawings.

The object of our invention is to provide toboggans which will combinesuitable lightness and convenience, the greatest possible strength anddurability, and which will present on their under sides frictionalsurfaces of lesser extent than the tobeggans heretofore generallygpi;

usebour invention being in part an improveinthe application of W'illiamH. Proctor and S. H.1Miller, Serial No. 191,961, filed February 15,1886.

In the accompanying drawings, Figure lA is a plan view of a tobogganembodying our invention. Fig. 2 is a side view, partly in section, ofthesame. Fig. 3 is a cross-.section on the line 3 3,- Fig. l; and Fig. 4 isa cross-sec. tion showing a slightlyn'ioditied fo'rm of our invention.

The body of our toboggan is composed of ilat thick and thin strips A,secured together by cross-bars B, through which latter pass screws binto the strips A, as in the application of Proctor and Miller, abovereferred to, the weight of the toboggan and its load being sustained bythe thick strips only, as in the toboggan described by the saidapplication.

To prevent the thin strips from pulling off from the screws Z), shouldVtoo much weight come on said strips, all of the strips are ,beveled attheir edges, as clearly shown in Fig. 3, the thick strips beingundercut, so that thev dovetailed or flaringlips a at the edges of thethin strips will be received into the undercut or beveled recess at theedges of the thick As all of the strips are closely tted together, it isobvious that by beveling the edges of the strips in the manner shown thethin strips will be supported at their edges throughout their entirelengths by the thick strips, so that liability ci starting them from theattachingscrews b will thus be avoided.

Instead of beveling the edges of the strips,

Serial No. 195,818. (No model.)

as shown in Fig. 3, the thin strips may be supported by smallrectangular lips a on their edges, fitting in corresponding undercutgrooves at the edges of the thick strips, as shown in Fig. 4; but thisconstruction, although serving a very good purpose, we do not considerso good as that shown in Fig. 3, for the reason that the beveled lips atthe edges of thestrips are stronger than the rectangular lips, as willbe obvious; but whether the strips are beveled, as shown in Fig. 3or

provided with rectangular lips and grooves,

as in Fig. 4, it will be apparent that the thinner strips will haveprojecting lips at their edges Yfitting in undercut grooves in thethicker strips. Y

C denotes the side rails of the toboggan these side rails beingpreferably secured in place by means of flexible fastenings c,consisting of thongs of gut or rawhide; or they may be ofwire or otherstrong but flexible material. These iiexible i'astenings may extendthrough the strips A, or may be passed only. beneath the cross-bars B,both of these arrangenlentsof the fastenings being shown in Fig. 2, andthe latter arrangement being considered preferable, for the reason thatit will not mar the smoothness of the under side of the strips A. Toraise the side rails, C, asuicient distance above the strips A to permitthe former to be grasped readily in carrying the toboggan, or in holdingonto the same in riding without making the cross-bars B unnecessaril ythick and heavy, we place small blocks beneath the said side rails andabove the crossbars, said blocks being preferably grooved, as shown, forthe reception of the side rails.

Having t-lms described our invention, we claim and desire to secure byLetters Patentl. A toboggan the body of which is composed of at stripsof varying thickness, the thin strips having at their edges projectinglips, and the thick strips having undercut grooves, in which the saidlips fit, substantially as set forth.
